a proper place for on account of uniting several structural details 
which are found separately in other families, thus, the general 
shape of the species before us is that of a Chrysomela rather than 
a Halticide, while the scarcely thickened posterior femora do not 
suggest the lattes family for its reception, yet, the broad elytral 
epipleuræ, distinct prosternum, closely approached antennæ agree 
better with this section ; the unarmed tibiæ however are again an 
exceptional structure amongst almost the entire tribe of Halticinæ, 
-andit is almost equally right to place the insect in the Galerucinæ 
proper; to further augment the difiiculty, the third joint of the 
tarsi is scarcely bilobed, as in the true Chrysomelidae, but the 
filiform palpi and closely approached antennæ forbid the reception 
of the insect into the last named group. In general shape and 
partly in structure, the species here described resembles the spe- 
cies Myrcina spectabilis Baly from Madagascar. 
Myrcinoides viridis n. sp. 
Below black, above metallic green or obscure cupreous,antennæ 
black, thorax very closely and finely punctured, elytra convex, 
punctured like the thorax. 
g Antennæ rather longer than the entire body, the basal 
joints strongly thickened. 
Q Antennæ much shorter, the basal joints scarcely thickened. 
Length 4 1/2 lines. 
G Head impunctate at the vertex, the frontal elevations broadly 
flattened, contiguous with the clypeus, the latter triangularly 
thickened, eyes narrow and elongate, labrum piceous, with a 
row of punctures, palpi obscure dark fulvous, the apical joint 
pointed, of half the size than the preceding one; antennæ black, 
the first joint strongly incrassate, club-shaped, the second very 
short, the third joint longer than the fourth, its apex like that 
of the following joints thickened, the terminal five joints shorter 
and much thinner ; thorax three times broader than long, the sides 
straight at the base, slightly rounded anteriorly, the anterior 
angles produced forwards, thickened, posterior margin slightly 
produced at the middle, with a very narrow and rather obsolete 
perpendicular grove at each side, the surface finely and very 
closely punctured, metallic green; scutellum purplish or black, 
impunctate, not longer than broad; elytra strongly convex, of 
the same colour and punctuation than that of the thorax, their 
epipleuræ extremely broad, concave and transversely wrinkled ; 
underside and legs black.
